Buyer beware, looking at E bay yesterday I lost count of how many people selling these cameras said in their specification that it had "a blackout less pelical mirror" which is completely untrue for the standard F1N and very misleading for any buyer, the only F1N that has a pelical mirror is the special H.S.(High Speed)version) with built in motor drive developed for the 1984 L.A summer Olympics that can shoot fourteen frames a second that would probably shatter a conventional reflex mirror and none of them advertised were these.
